A control apparatus for a vehicle drive-force transmitting apparatus that includes a gear mechanism and a continuously-variable transmission mechanism. The control apparatus determines whether there is a lower-gear-ratio setting request requesting a target gear ratio of the continuously-variable transmission mechanism to be set to a lower gear ratio that is lower than a highest gear ratio of the continuously-variable transmission mechanism. When it is determined that there is not a detection accuracy of a rotational speed of an output rotary member of the drive-force transmitting apparatus, the control apparatus sets the target gear ratio to the lower gear ratio if it is determined that there is the lower-gear-ratio setting request, and sets the target gear ratio to the highest gear ratio if it is determined that there is not the lower-gear-ratio setting request.

A lamination for use in an integrated drive generator is formed from a plurality of plates having a body including a pair of opposed cylindrical surfaces. Non-cylindrical ditches are defined circumferentially intermediate the pair of cylindrical surfaces. A plurality of passages are formed in an outer periphery of the cylindrical surfaces including relatively large holes extending through a slot to the outer periphery. Grooves are formed intermediate the relatively large holes.

A control apparatus for a drive-force transmitting apparatus that includes a transmission having primary and secondary pulleys. The control apparatus calculates a target thrust applied to the secondary pulley such that the target thrust is larger during a vehicle driven state than during a vehicle driving state. The control apparatus sets a first determination threshold of a drive-force related value used to determine whether it is the vehicle driving state or vehicle driven state and a second determination threshold of the drive-force related value used to switch from determination of the driven state to determination of the driving state, such that a difference of the first and second determination thresholds is larger and a range of the drive-force related value in which the driven state is determined is wider, when an automatic running-speed control is executed, than when the automatic running-speed control is not executed.

A dog clutch of a vehicle power transmission device includes a sleeve, the dog clutch connecting/disconnecting a first rotating shaft to/from a first gear by moving the sleeve between a neutral position at which inner circumferential teeth formed on an inner circumferential side of the sleeve are not meshed with outer circumferential teeth on a side surface side of the first gear and an engagement position at which the inner circumferential teeth are meshed with the outer circumferential teeth, the inner circumferential teeth and the outer circumferential teeth having inclined surfaces tooth thicknesses of which become larger as the inner circumferential teeth and the outer circumferential teeth approach each other, and when the sleeve is moved to an engagement position by a shift fork, the sleeve being held in contact with a side surface of the first gear.

A propulsion control system provides different levels of jerk as a function of operator inputs and actual measured operational parameters in a machine. The system includes a power source, a continuously variable transmission (CVT) coupled to an output of the power source, a plurality of input/output devices, a plurality of sensors configured to generate signals indicative of operational parameters of the machine, and a controller communicatively coupled with the power source, the CVT, the input/output devices, and the sensors. The controller includes a database stored in a memory with a plurality of jerk values mapped to different operations of the machine selected from at least one of activation of a brake by an operator for an aggressive stop, a directional shift request from an operator to select one of forward, reverse, or neutral, and a set of operating conditions of the machine indicative of a blade load shedding mode. A jerk selection module is programmed to select at least one of a jerk value, an acceleration limit value, and a deceleration limit value based on a current operation of the machine. A speed command generating device is programmed to integrate a selected jerk value twice to generate a desired speed command. A proportional-integral-derivative (PID) control device is configured to continuously calculate a control error between the desired speed command and an actual speed of the machine. An output command control module is configured to output a control command for implementing a change in an output torque to at least one of the power source and the CVT to reduce the control error.

A drive system for a vehicle includes first and second electrical machines, a transmission, and an electrical energy supply. The transmission includes first and second gear sets, a connecting shaft coupled to the first gear set, a driveshaft configured to transport power from the electrical machines to a tractive element of the vehicle, and a clutch. The first gear set is coupled to the first electrical machine. The second gear set is coupled to the second electrical machine. Carriers of the first and second gear sets are coupled. The clutch selectively rotationally couples the carriers to the driveshaft when engaged. The drive system operates in an electric only configuration whereby the electrical energy supply provides electrical energy to at least one of the electrical machines to drive at least one of the connecting shaft and the driveshaft without a mechanical energy input to the transmission from an engine.

A control apparatus for a vehicle drive-force transmitting apparatus which establishes selectively a first state in which a drive force is transmitted by a gear mechanism and a second state in which the drive force is transmitted by a continuously-variable transmission mechanism. The control apparatus executes a shift-up action requiring the first state to be switched to the second state, in (a) a case in which a state of the drive-force transmitting apparatus satisfies a first condition that a gear ratio of the continuously-variable transmission mechanism is not lower than a first gear ratio value and in (b) a case in which the state of the drive-force transmitting apparatus satisfies a second condition that a lap-down control is executed with the gear ratio of the continuously-variable transmission mechanism being not lower than a second gear ratio value that is lower than the first gear ratio value.

Devices and methods are provided herein for the transmission of power in motor vehicles. Power is transmitted in a smoother and more efficient manner by splitting torque into two or more torque paths. A continuously variable transmission is provided with a ball variator assembly having an array of balls, a planetary gear set coupled thereto and an arrangement of rotatable shafts with multiple gears and clutches that extend the ratio range of the variator. In some embodiments, a locking clutch is operably coupled to the planetary gear set to selectively couple two of the elements of the planetary gear set during operation. Engagement of the locking clutch corresponds to a fixed ratio operating mode. Disengagement of the locking clutch corresponds to a variable ratio operating mode.
